3 Connecting to a network

Your computer can travel with you wherever you go. But even at home, you can explore the globeand access information from millions of websites using your computer and a wired or wirelessnetwork connection. This chapter will help you get connected to that world.

Connecting to a wireless networkWireless technology transfers data across radio waves instead of wires. Your computer may beequipped with one or more of the following wireless devices:

● Wireless local area network (WLAN) device—Connects the computer to wireless local areanetworks (commonly referred to as Wi-Fi networks, wireless LANs, or WLANs) in corporateoffices, your home, and public places such as airports, restaurants, coffee shops, hotels, anduniversities. In a WLAN, the mobile wireless device in your computer communicates with a

wireless router or a wireless access point.● HP Mobile Broadband Module (select models only)—A wireless wide area network (WWAN)

device that gives you wireless connectivity over a much larger area. Mobile network operatorsinstall base stations (similar to cell phone towers) throughout large geographic areas, effectivelyproviding coverage across entire states, regions, or even countries.

● Bluetooth device (select models only)—Creates a personal area network (PAN) to connect toother Bluetooth-enabled devices such as computers, phones, printers, headsets, speakers, andcameras. In a PAN, each device communicates directly with other devices, and devices must berelatively close together—typically within 10 meters (approximately 33 feet) of each other.

For more information about wireless technology, see the information and website links provided inHelp and Support. From the Start screen, type help , and then select Help and Support .

Using the wireless controlsYou can control the wireless devices in your computer using these features:

● Wireless button, wireless switch, wireless key, or airplane mode key (referred to in this chapteras the wireless button) (select models only)

● Operating system controls

Using the wireless button

The computer has a wireless button, one or more wireless devices, and, on select models, one or two

wireless lights. All of the wireless devices on your computer are enabled at the factory, and if yourcomputer has a wireless light, the wireless light is on (white) when you turn on the computer.

The wireless light indicates the overall power state of your wireless devices, not the status ofindividual devices. If the wireless light is white, at least one wireless device is on. If the wireless lightis off, all wireless devices are off.

NOTE: On some models, the wireless light is amber when all wireless devices are off.

Because the wireless devices are enabled at the factory, you can use the wireless button to turn on orturn off the wireless devices simultaneously.

Using operating system controls

The Network and Sharing Center allows you to set up a connection or network, connect to a network,and diagnose and repair network problems.

To use operating system controls:


2. Select Network and Internet , and then select Network and Sharing Center .

For more information, from the Start screen, type help , and then select Help and Support .

Sharing data and drives and accessing softwareWhen your computer is part of a network, you are not limited to using only the information that isstored in your computer. Network computers can exchange software and data with each other.

Using a WLANWith a WLAN device, you can access a wireless local area network (WLAN), which is composed ofother computers and accessories that are linked by a wireless router or a wireless access point.

NOTE: The terms wireless router and wireless access point are often used interchangeably.

● A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access pointsthat can accommodate a large number of computers and accessories and can separate criticalnetwork functions.

● A home or small office WLAN typically uses a wireless router, which allows several wireless andwired computers to share an Internet connection, a printer, and files without requiring additionalpieces of hardware or software.

To use the WLAN device in your computer, you must connect to a WLAN infrastructure (providedthrough a service provider or a public or corporate network).

Using an Internet service provider

When you are setting up Internet access in your home, you must establish an account with anInternet service provider (ISP). To purchase Internet service and a modem, contact a local ISP. TheISP will help set up the modem, install a network cable to connect your wireless router to the modem,and test the Internet service.

NOTE: Your ISP will give you a user ID and a password to use for Internet access. Record thisinformation and store it in a safe place.

Setting up a WLAN

To set up a WLAN and connect to the Internet, you need the following equipment:

● A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased froman Internet service provider

● A wireless router (2) (purchased separately)

● A wireless computer (3)

NOTE: Some modems have a built-in wireless router. Check with your ISP to determine what typeof modem you have.

The illustration below shows an example of a wireless network installation that is connected to theInternet.

As your network grows, additional wireless and wired computers can be connected to the network toaccess the Internet.

For help in setting up your WLAN, see the information provided by your router manufacturer or yourISP.

Configuring a wireless router

For help in configuring a wireless router, see the information provided by your router manufacturer oryour ISP.

NOTE: It is recommended that you initially connect your new wireless computer to the router byusing the network cable provided with the router. When the computer successfully connects to theInternet, disconnect the cable, and access the Internet through your wireless network.

Protecting your WLAN

When you set up a WLAN or access an existing WLAN, always enable security features to protectyour network from unauthorized access. WLANs in public areas (hotspots) like coffee shops andairports may not provide any security. If you are concerned about the security of your computer whenconnected to a hotspot, limit your network activities to email that is not confidential and basic Internetsurfing.

Wireless radio signals travel outside the network, so other WLAN devices can pick up unprotectedsignals. Take the following precautions to protect your WLAN:



31/79

● Use a firewall.

A firewall checks information and requests that are sent to your network, and discards anysuspicious items. Firewalls are available in both software and hardware. Some networks use acombination of both types.
